In fact, it is rare for such symptoms to be caused by falling blood sugar levels after eating, with the actual cause for many people often relating to what food was eaten or variations in the timing of the food moving through the stomach and intestinal tract.

If there is no hypoglycemia at the time of the symptoms, you may have what is known as "postprandial syndrome".

Treatment

No medical treatment is usually required for cases of reactive hypoglycemia. Instead, patients are generally advised to:

Further evaluation by a doctor may be required for some people, such as those who have had intestinal surgery (e.g. gastric bypass).

Can hypo unawareness be dangerous?

Reduced hypo awareness can potentially be dangerous. If you suffer hypoglycemia you should be careful to test before putting either yourself or others in any potential danger.

Examples when hypoglycemia and unawareness of it could be particularly dangerous include driving, operating dangerous machinery at work and even day to day tasks such as cooking or even crossing the road.

Improving hypo awareness signs

If you are suffering from impaired hypo unawareness, you may be advised to increase your window of blood glucose control for a period of time to get your numbers higher and prevent hypos from occurring so often.

Studies have found this method to be successful.

If you have frequent hypos you may need to test your blood sugar more often, to help get better control as well as to catch hypos earlier. Try to record which events lead to hypos so you can spot trends and prevent them in future.
